T 0 oil whom it may concern Be it known that l, ULYssEs G. BnA'rrv, a citizen of the United States, residing at l 'olt Summit, in the county of Harrison and State of West Virginia, have invented ce tain new and useful Improvements in (kmnecting-Sockets; and I do hereby de (flare-the following to be a full, clear, and QYEZLCb description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Tihis invention relates to connecting sockets used. in the structural joints of metallic building structures, such as oil Well derriclrs; and it consists of a sp socket as hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of a portion of a derrick provided with a joint socket according to this invention. Fig. 2 plan. view of the same. Fig. 3 is a de view the socket. Fig. 4 is a of the socket looking at it from ;-nreo-quarters of a circle and having l s of lugs 42 and 5 arranged radially 1 edge and at substantially a right s each other:

e piece 3 is a plate extending about oneter a circle, and having a series of w and '4' at each edge, arranged to corond the lugs 4E and All the lugs We bolt holes 8, and the tips of the lugs nd 8 welded together or are otherwise anently secured together. The socket ormed of metal which is more or less -l at or flexible, and in its normal condiits two pieces 2 andki are sprung apart, 1mm in Figs. 3 and 4, so that the lugs are separated. A narrow convergis formed between the main porthe lugs and 6, extending from elded tips to the socket segments 2 this ap is arranged radially of the edges of the pieces have beveled surfaces 9 to permit free movement of one part with relation to the other.

The vertical members or tubes 10 of the derrick are placed in the end portions of the socket. with their ends in abutment against each other, when the pieces of the socket are sprung apart. Three lugs are pref? erably provided on each edge of each piece, but more or less than three lugs can be used. The horizontal braces 11 of the derrick are bolted to the middle lugs, and the inclined braces 12 are bolted to the topnnd bottom lugs. The fastening bolts 14 which pass through the holes in the lugs 5 and 'Z and in the braces 11 and 12 also contract the two pieces of the socket upon the vertical members or tubes 10, so that all the said. parts are firmly secured together, and no special bolts are required for clamping the socket to the tubes 10.

As the two pieces of the socket; are welded together at the tips of their lugs they never get lost and always preserve their relative positions. The exact register of the bolt holes in the lugs is assured, and the socket can be used on tubes which vary somewhat in size, as the pivotal attachment of one" piece to the other by the tips of their lugs enables the curved parts of the socket to be sprung apart to a considerable extent, and Without being distorted or bentout of shape.

It is not necessary that the lugs should be exactly radial of the center of the soclget,

and the lugs 5 are preferably arranged a little to one side of the radial line as shown in Fig.

\Vhat I claim is:

In a metallic building structure, a contractible connecting socket comprising two cylindrical segments of unequal circumferential; length, each segment having at side edges a series oi? lugs provided with bole holes and arranged in pairs, one series of pairs of lugs being arranged at a right angle to the other series, the adjacent surfaces of the tips of the lugs of one series being welded together beyond the bolt holes and the lugs of the other series being separated from each other; in combination with up- V In testimony whereof I have aflixed my rights inserted in the end portions of the signature in the presence of two witnesses. 10 socket, two series of braces, and fastenlng bolts which secure the two series of braces to 5 the respective series of pairs of lugs, the fas- ULYSSES BEATTY' tening bolts which pass through the sepa- Witnesses: rated higs operating also to contract the W.
